Timberwolves television broadcaster Jim Petersen returned to work Saturday night, three days after suffering a heart attack he said was nowhere near the "mild" one the team reported he had after Wednesday morning's shootaround.

Petersen credits a telephone call to team physician Sheldon Burns with saving his life. Burns urged him to call paramedics immediately rather than wait for his wife to arrive home after he went from experiencing slight discomfort in his chest to a crushing pain in a matter of minutes.

Within 50 minutes after calling for help, Petersen rested in the hospital with a stent in his heart to open what he called a 100 percent blockage.
